Worth stating the units and the reference range whenever you post a number here.

This answered a question I did not know how to ask. Adding it to my notes with a link back to this thread.

Clinical perspective, offered as context rather than as advice. Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then measure again under the same conditions.

Adding a me-too, because a thread of one person's experience is not much use. I had assumed I was the exception until I read this.

There is a second half to this that has not been said yet. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.

Ask again with the specifics and you will get a better answer than this one.

One concrete data point for the thread. One practical note: write down what you did and when, before you need it. Reconstructing a timeline from memory three months later is how people end up unable to answer the one question that would have resolved it.
